A long, long time ago, we used CoolEdit Pro to record and mix our music. This would have been around 2001, on an ancient desktop running a processor at 300 MHz, in our mockup home "studio." At that time, CoolEdit was impressive. I can rant about how great it was for a long time, but here is the important stuff.
10 years ago, I played with Samplitude – a powerful recording and mixing software. I liked it, because it was intuitive. Learning how to use it took little time.
The simplest way to change the pitch of a signal is to simply stretch it or compress it in time. This type of pitch shifting has a disadvantage though, as it also introduces a change in the timing of the signal – it speeds it up or slows it down. It can still be useful, if the signal is short or if its tempo is unimportant. It can be used, for example, for changing the tone of the drum samples used by drum machines or the notes of the wave samples used by MIDI wave mappers.
The following is an example frequency filter that combines the standard low pass FIR filter with a standard second order low pass Butterworth filter. We are doing this to show that we do not have to stick to the standard filter design, but can experiment. Relying on the standard filters is a start, but there is much we can do.
A few years back, I wrote a few posts about MIDI. Those posts were technical. They explained the messages that MIDI devices use to communicate with each other. Later, we moved most of this to the Wiki, but not all. Some notes, I thought, should come back.
We began uploading a series of updates to Orinj, starting with version 2.5.0 of March 11, 2016. As we are working to develop Orinj version 3, we are fixing bugs and applying cosmetic changes that can also be useful in version 2. There is no sense in waiting for version 3 to be ready. This can take some time. In the meantime, version 2 will be updated as often as needed.
A typical reverb is supposedly implemented in two parts. First, a tapped delay line is used to simulate the initial (early) reflections that may be few in number and distinct. Second, a Shroeder reverb is used to simulate the late reverb, which contains a large number of indistinct reflections. The Shroeder reverb itself consists of several sequential all pass filters, the output of which is fed through a several parallel feedforward comb filters (simple delays).
Digital Signal Processing for Audio Application. Second Edition was published on November 18, 2014. What's new in the second edition? A few things.
I am a bit behind the times. Until yesterday, I didn't even know SoundCloud.com existed. I do now, but only because I landed on a random tweet about it (thanks to Scottkerrmusic). I should have expected it. It was just a matter of time, before a site like SoundCloud pops up. This one has apparently been running for 6 years and already has over 10 million registered users, including some popular names in music.
Some time ago I received a copy of a book – The Music Producer's Survival Guide. Chaos, Creativity, and Career in Independent and Electronic Music – by Brian M. Jackson, published by CENGAGE Learning (ISBN-13: 978-1-285-19892-7, ISBN-10: 1-285-19892-1). First, I should apologize to the author and publisher for taking so long to write this. I was traveling over the past one month. And the book is dense.
